Set device location / name

According to the documentation any device that is part of an Integration should be able to have an area set. However, this does not appear to apply to Zwave devices as all of mine show No Area. I also cannot seem to rename the device and there have issues like 10+ Jasco Products 12722 On/Off Relay Switch devices in the list and until I click into them cannot tell which is which.

Looking for suggestions to fix both of these issues. Thanks in advance!
